irga5000 [103]

Answer:

The perfect square ( x -1 )² = 2

Answer:

A) (x +2)(x -3)² = 0

Step-by-step explanation:

Synthetic division by (x-3) gives the quadratic x² -x -6, which has factors (x -3) and (x +2). This is confirmed by another round of synthetic division.

The resulting factorization is ...

... (x +2)(x -3)² = 0

_____

A graph confirms a double zero at x=3 and one at x=-2.

(33-3) division symbol 10-5 with an exponent of 2
lianna [129]

Answer: The answer is -22.

Step-by-step explanation:

Our problem is (33-3) ÷ 10-5^2. We can use PEMDAS to solve it.

First, let's eliminate the parenthesis. 33-3 is 30. The problem is now 30 / 10-5^2.

Next, let's get rid of our exponent. 5 to the second power is the same as 5 x 5 which is 25. The problem is now 30 / 10 - 25.

Then, we have to do division before subtraction. 30 / 10 is 3.

Lastly, 3 - 25 is -22.
